As shown in Reference will now be had to the drawing, Figures 1 and 2, the discharge end i! has a screw- I wherein like numerals of reference designate corthreaded adapter l8 used for receiving a threaded responding parts throughout the several views, coupling 22 (Figure 5) attached to aspray nozin which: zle 23. The hose may be heavier than spray tub- Flgure 1 is a side elevation of my faucet coning and cause the faucet connection to lose its nection in operative position on a conventional grip on the faucet nozzle. For the purpose of I faucet. augmenting the grip of the faucet connection on are substantially in adjoining relation and diametrically in alinement.

When the faucet connection I0 is gripped in the hand of the user, the hand pressure is transmitted internally against the said suction cups and causes the rubber cups to be substantially equally and jointly flattened against the nozzle. This pressure causes the air normally in the cups to be forced out therefrom into the lower end of the device and to flow out through the attached hose. The grip of the faucet connection onthe faucet nozzle is thus augmented-by atmospheric pressure transmitted to the sleeve by reason of reduced pressure within the suction cups. I may provide a radially projecting rib 2| centrally of each cup, the said ribs being of less height than the depth of the cups. When the hand of the user grips the shell H for attaching the faucet connection ill to a nozzle 24 of a faucet 25, he causes a circumferential twisting pressure on the shell. This twist causes the ribs 2| to move away from their radial positions and to permit the suction cups 'to be flattened against the nozzle 24 and cause the escape of the air normally therein.

I may provide longitudinal or axially positioned ribs 26 on the outer surface of the shell H to secure a better grip on the shell.

Figure 4 shows a modified faucet connection 21 similar to the faucet connection [0 shown in Figures 1 to 3 inclusive, but having ribs 28, 2B, connecting the sleeve 29 with the outer shell 30. The ribs 28 and the cups 8| are in diametrical alinement in the shell 30 with outer ribs 33 which are axially positioned on the outer surface of the shell 10. The discharge end 34 has a metal sleeve 35 and a central nipple 36 upon which may be secured a rubber tube.

It is to be noted that when a faucet nozzle of large external diameter is inserted into the internally tapering sleeve l3 that when the said nozzle reaches the small lower end of the sleeve, the walls of the sleeve at this point may be stretched to such an extent as to completely close the entrance into the annular channel ii. In

such an event this closing of the lower end ofthe channel I6 willprevent the water from entering the channel and will prevent the water pressure from augmenting the grip of the sleeve l3 on the nozzle. The ribs", 2! connecting the sleeve 2 9 with the outer shell 30 prevent such an occurrence by ,causing enlargement of the outer shell concomitantly with the enlargement of the sleeve.

Due to the thin upper connecting wall l2 which is of the same thickness asthe sleeve l3 and the wall- I! of the body II, the channel It is of maximum height and this produces a, long gripping surface on thenozzle.

In accordance with the patent statutes I have described and illustrated two embodiments of my invention, but it will be understood that various changes can be made therein without departing from the spirit of the invention as deflned by the appended claims.

I claim: I

l. A detachable coupling for securely connecting a hose to, a faucet, comprising a rubber body having an outer shell adapted at the lower end for connection to a hose, the upper end of said body having an inwardly extending annular flange, said flange having a downwardly extending sleeve, said sleeve having spaced air pockets intermediate its upper and lower ends and forming suction cups for gripping a faucet nozzle, a plurality of longitudinal ribs connecting said sleeve and the inner surface of said outer shell, and the said inner ribs and said suction cups being diametrically in alinement.

2. A faucet connector for heavy hose, comprising a rubber body having an outenshell adapted at the lower end for'connection to a hose, the upper end of said body having an annular flange and a downwardly extending sleeve, said sleeve having air pockets in diametrically opposed relation, said pockets beingadapted to be flattened by external manual pressure, and means in diametrical alinement withsaid pockets and positioned intermediate said sleeve and the inner surface of said outer shell for flattening said pockets when said outer shell is gripped by a human hand.

3. In a detachable coupling for securelyconnecting a hose to a faucet, comprising a rubber V body having an outer shell adapted at the lower end for connection to a hose, the upper end of said body having an inwardly extending-annular flange, said flange having a downwardly extending sleeve spaced from said shell, and a plurality of longitudinal ribs connecting said sleeve and the inner surface of said outer shell in said spaced relation.
